Live Updates: How Bad Is the Flu This Year?

The GoodRx Research Team has been tracking the flu this year by monitoring fills for Tamiflu (oseltamivir), the most common flu treatment. It seems as if we have reached the end of this  season.

How many people are filling Tamiflu prescriptions?

During the week of March 23, 2020, Tamiflu fills accounted for 0.12% of all drugs filled in the U.S. This season, we officially reached fill rates that we saw in the 2017-2018 flu season, which was a notoriously bad year. But the flu season ended as the novel coronavirus (COVID-19) pandemic swept across the U.S.

Which states had the most Tamiflu fills?

Even though Tamiflu rates are declining, most states are still seeing high flu-like activity according to the Centers for Disease Control and Prevention (CDC). However, some states like Arizona, Florida, and Idaho are seeing low to moderate flu-like activity.

Though there is a flu vaccine available, Tamiflu is often prescribed if symptoms start to appear, which helps explain the recent surge in prescriptions. If taken within the first 48 hours of getting the flu, Tamiflu can work to block the actions of influenza in your body, and shorten the duration of the virus.

Methodology: Tamiflu prescription fill rate is based on a statistically significant sample of fills at U.S. pharmacies. Data comes from several sources, including pharmacies and insurers, and provides a representative sample of nationwide U.S. prescription drug volume.
